Larger (more massive) BH mass distributions in BH-BH mergers within design advanced-LIGO sensitivity (z <  2) for models M60.B, M70.B, M30.B, M10.B, M50.A, M50.B. Power-law fits (dashed black lines) were performed for model M30.B in the top panel (∝M^−3.6), and for models M50.A (∝M^−2.3) and M50.B (∝M^−2.4) in the bottom panel in the log-log space. These distributions can be compared with other theoretical predictions (e.g., Fig. 1 of Mapelli et al. 2019, or Fig. 4 of Stevenson et al. 2019 that seem to be close to ∝M⁻² − M⁻³; we note that power-laws shown in the latter work are not correct) or with the LIGO/Virgo observational estimate of ∝M^−1.6 with large uncertainty on the power-law index: ∝M^+0.1 − M^−3.1 (Fig. 1 in Abbott et al. 2019a). Some of our models (e.g., top panel) show somewhat steeper relations, while other models (bottom panel) are in agreement with LIGO/Virgo estimate.
